Pyramid:
A pyramid is a polyherdron consisting of a bas, which is is a polygon,and three or more lateraql faces.
Surface Area and volume of pyramids
V= BH or pie(r^2)h
v = volume
B = base area
H = height
s=1/2lp+B
vertex of the pyramid- the lateral faces are triangles that share a single vertex lateral faces= triangles that share a single vertex.
lateral edge= intersection of two lateral faces.
regular pyramid= a pyramid whose base is a regular polygonand whose lateral faces are congruent isosceles triangles
slant height= length of an altitude of a lateral face of a regular pyramid
pyramids are named by the shape of there base.
SA of a regular pyramid: S=L+B or S=1/2lp+B (S= surface area, L= lateral area, B base area, p= perimeter of base, l= slant height.) RECTANGULAR PYRAMIDTRIANGULAR PYRAMID HEXAGONAL PYRAMID
